METHOD OF MAKING ROOFINGELEMENTS.

Patented Sept. 21, 1915.

Application filed January 21, 1915. Serial No. 3,481.

To all whom it may concern:

Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States, and a resident of Montclair, in the county of Essex and State'of New Jersey, have invented certain new and useful Improvements in Methods of Making Roofing Elements, of which the following is a specification. v

This invention relates to a process of making waterproof coverings for roofs or side walls, such as may for simplicity be termed roofing elements, and it has for its object to provide a novel and economical method or process of making such elements.

According to my invention, I deposit upon I the plastic coating ofia waterproofed sheet of fibrous material bands or stripes of grit, such as crushed mineral material. Then, if

desired, I deposit upon the interveningspaces grit of another color, shade or tint, thereby producing a novel and highly ornamental efi'ect. If desired, the sheet may then be severed transversely into strips of the same length and breadth. \Vhen thus severed into strips, the elements so formed may be laid horizontally in vertically overlapping rows, with the stripes or bands of one row either registering with or else breaking joint with those of the adjacent rows, to produce different effects. The stripes or vbandsof grit are produced by effecting a relative movement of the sheet and the hop pers or containers for the grit, as for example by feeding the sheet longitudinally beneath the ports leading from the hoppers, in which case the stripes or bands will be straight, but, by effecting at the same time a relative lateral movement of the sheet and the hopper, the stripes may be formed in curved or undulating lines to produce very pleasing effects. The roofing element may thus be in the form of a sheet, or else the sheet may be. cut or severed into pieces of small size of the desired configuration.

On the accompanying drawings, I have illustrated conventionally roofing elements embodying the invention, and simple instrumentalities which may be employed in their manufacture.

Referring. to said drawings, Figure 1 illustrates in plan view a machine which may be used for supplying grit to form on a different color.

differently colored grit. Fig.2 shows a side elevation of the same. Figs. 3 and 4 illustrate sections through the hoppers for feedlng the grit. Fig, 5 represents a portion of the sheet having the stripes and bands of grit embedded therein. Fig. 6 represents a shingle strip cuttherefrom. Fig. 7 repre-- sents a section through the element on the l1n e 7-7'of Fig. 6. Fig. 8 shows how the shlngle strips may be laid.

As a body or foundation, I employ any applying to one or both faces thereof a coating of Waterproof adhesive material such as pitch or asphaltum in a soft and plastic state. After "passing the rolls, the sheet is fed beneath hoppers 12, 18, or other forms of distributing or feeding devices for applymg the grit to the soft coating thereon.

The first hopper is shown as having separated deliverv. spouts or apertures 14, 14, through which grit of one color, say green, slate or black, may be dropped in separated streams upon the sheet traveling therebeneath, so that the grit will adhere to the coating in continuous and substantially parallel stripes 18. Bv reciprocating the hopper endwise, Wavy or undulating stripes may be produced. In the hopper 13, the grit, which may for example be red, brown or of any other contrasting color, tint or shade, is dropped in a thin sheet upon the striped foundation sheet, and the grit which engages the uncoated portions of the adhesive coating will adhere thereto. The sheet may then be passed through one or more pairs of pressure and cooling rolls 16, 17 to embed the adhering grit into the adhesive coating, and, as the sheet passes over and through the rolls, those portions of the grit from the hopper 13, which fall upon the stripes of grit from the hopper 12, fall off or are dislodged, leaving the stripes showing with intervening bands or spans 19 of a A fan or blower may be usedfor blowing the loose grit ofi from the stripes, at a point between the hoppers and the first pair of rolls. From the final rolls the sheet maybe wound up in a suitable roll and used in sheet form or else it [may be then advanced to a cutting machine not shown, to be cut transversely to form what I term shingle strips. In such case, the lines of division may be say 10 inches apart, so that each finished element will be approximatelv 40 inches in length and 10 inches in width or height, as shown in Fig. 6.

The width of the several stripes'and the intervening bands may vary, but I have found that stripes approximately from to 1 inch wide produce'a pleasing effect. The number of transverse or vertical stripes on the individual elements may be varied, and they may be formed equal distances apart, or at varying distances, to produce any desired design. If desired, one end -margin of the element may be striped and the other unstriped, as shown in the lastmentioned figure, so that, when the ends of the elements are abutted as shown in Fig. 8, the stripes if parallel will be evenly spaced. If desired, however, the grit may be omitted from a narrow space at either or both ends of the element, to permit them to be overlapped lengthwiseof the row, when laid.

If desired, the hopper 13 may be provided 'with partitions 20to contain grit of different colors in the compartments formed thereby. These partitions may register with the spouts or nozzles of the hopper 12, so that the bands or lines of grit between the stripes will differ in color therefrom and from-each other to produce a variegated and ornamental effect.

In Fig. 7, which illustrates a lengthwise section through ashingle strip,

the impregnated and waterproofed foundation is indi-' cated at 10, and the waterproof coating at 22, the stripes of grit at 18, and the intervening bands of grit at 19.

I have herein referred to the formation of stripes and bands merely for the purposes of description. It is quite evident that the width of the stripes and bands may be varied as deemed advisable, so that the stripes may be as wide or wider than the bands of grit. In some cases, in. lieu of supplying the second hopper, under which the sheet travels, with crushed mineral of the nature of slate, granite or the like, I may supply the second hopper with pulverized mice. or with talc so that the parallel spaces between the stripes will be left uncoated with grit but be prevented from sticking to adjacent layers or convolutions of the roofing material. In this case, the stripes will in all probability be much wider than they are shown, this being permitted by employattempting to set forth all of the forms in which it may be made or all. of themodes of its use, what I claim is:

1. A method of making roofing elements which consists in embedding longitudinal stripes of crushed mineral material in the adhesive coating of a sheet of roofing material, and then cutting said sheet transversely to form strips having said stripes crosswise thereon.
